It appears that there is a bug in Zend_Config_Xml when using it without
specific sections ($conf = new Zend_Config_Xml('file.xml', null);).
Since the _toArray() function does not check if the simplexmlobject only
contains a string, an empty Zend_Config obj is returned.
This only happens on the 2nd level element in the xml files as specifying
null in will use the first level elements to extend from.
Examples:
application
home../application/home
namespace
foofoo/foo
/namespace
/application
$conf-home will return an empty Zend_Config obj not the expected string.
$conf-namespace-foo will return as expected a string.
I simply added an if else to check if the simplexmlobject has children, if
not then return the string.
Zend_Config_Xml
/**
* Returns an associative and possibly multidimensional array from a
SimpleXMLElement.
*
* @param SimpleXMLElement $xmlObject
* @return array
*/
protected function _toArray($xmlObject)
{
$config = array();
if ($xmlObject-children()) {
foreach ($xmlObject-children() as $key = $value) {
if ($value-children()) {
$config[$key] = $this-_toArray($value);
} else {
$config[$key] = (string) $value;
}
}
} else {
$config = (string) $xmlObject;
}
return $config;
}
